CABLE-HANGER.

Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed July 27, 1916. Serial No. 111,653.

To all ZIJiLOhL it may concern.

Be it known that 1, CHARLES MAssoN, a subject of the King of Great Britain, and resident of the city of vlontreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Cable- Hangers, and do hereby declare the following to be a full, clear, and exact description of same.

This invention relates to hangers for up holding cables of underground conduit sys-" tems and appertains particularly to hangers for use in man-holes and the like.

An object of the invention is to simplify the construction and use of cable hangers and to so support the same as to facilitate changing thereof while the cables are pre, out and avoid undue disarrangement of the cables when such change is taking place.

For full comprehension, however, of my invention reference should be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate the same parts and wherein:

Figure 1 is a side elevation of the hanger and supporting bracket, the Wall of a manhole being shown in section;

Fig. 2 is a face view of same; and

Fig. 3 is a perspective of the hanger detached and viewed from the rear.

Referring now to the drawings 2 indicates the supporting bracket for the hangers, there being provision for the support of a suitable number of hangers upon each bracket. The bracket consists preferably of a length of angle-iron arranged vertically within the man-hole, one flange being adapt ed to rest flat against the wall 3 of the manhole and being provided with holes through 'which fastening bolts l are inserted to secure the bracket to the wall. The other flange 5 extends outwardly from the wall and has a series of vertically arranged notches 6 therein each of which consists of a portion 6 extending inwardly from the outer edge of flange 5 transversely of the latter and terminating in a portion 6 which extends downwardly in the longitudinal line of the flange, thus forming a series of inwardly and downwardly extending notches for supporting and positioning cable hangers.

The hangers each consists of a back 7 and a shelf portion 8 which latter extends outwardly from the back and is formed with an upwardly extending outer end 9 which with the back 7 forms a depression for the reception of cables, the shelf portions of different hangers being of varying extent for the accommodation of different humbers of hangers.

A pin or projection 10 extending trans versely to the shelf 8 is carried by the back 7 and adapted to be inserted in one of the notches and rest in the bottom of portion 6f thereof to uphold the hanger, the projection hearing against the outer wall of such portion which is preferably parallel. to the outer edge of the flange and with the back 7 which bears against the outer edge of flange 5 rigidly supporting the hanger, said pro ection being of just slightly less transverse extent than the width of the notch to prevent excessive play.

In the preferred construction the back '7 is formed with a rearwardly extending flange 11 near each side, the flanges being spaced apart to form a slot for the accommodation of flange 5 of the bracket so that when the hanger is attached to the latter the hanger flanges flank the bracket flange and prevent excessive lateral swinging of the hanger. The projection 10 takes the form of a permanently positioned pin or web which is carried between the flanges 11 and crosses the slot at a point spaced at a slightly greater distance from the back 7 or bottom of the slot than the extent of portion 6 of one of the bracket notches, to permit of the entry of the web into portion 6, the web being furthermore located between the top and bottom of the back 7 and preferably above the level of shelf 8 so that when hung upon the bracket the point of suspension is between the top and bottom of the back 7 and consequently the latter bears against the outer edge of flange 7 both above and below such point and prevents excessive vertical swinging of the hanger.

At times it becomes necessary to provide accommodation. for a greater number of cables than a hanger being used provides and this necessitates the removal of the hanger and its replacement by one with a greater shelf space. Heretofore this change presented the difiiculty that the cable or cables supported by the hanger then being used have to be raised rather high to clear the hanger and permit same to be disengaged from the bracket. I have avoided this difficulty to a considerable extent by curving each of the notches at the juncture 13 of the top wall of portion 6 and rear wall of portion 6 so that a cam face is presented at this point which on engagement therewith by web 10 upon the removal of the hanger causes the latter to tilt downwardly, the outer end of thesheli 8 being thus swung below the line of cables and the hanger, moving in a downwardly and outwardly inclined path, consequently more easily disengaged than would be the case were it necessary to disengage it through a straight path.

From the above it will be seen that the hanger in addition to being rigidly supported when. applied to its bracket and embodying the advantageous features previously mentioned is formed to present the least difiiculty in its application to the bracket in that b straddling the latter the hanger can be readily hooked into a notch even in dimly lighted surroundings, while the absence of separate fastening means which require attention after the hanger has been arranged in its proper position with respect to the bracket, avoids considerable inconvenience in the application of the hanger to the bracket.

What I claim is as follows:

1. A support for cables and the like, comprising a bracket having an inwardly and downwardly extending notch therein, a hanger adapted to straddle the bracket and a projection upon the hanger adapted to enter said notch. r

A support for cables and the like, comprising an angle-iron bracket, one flange of which has a notch therein extending in.- wardly from the outer edge of the flange and then downwardly, a hanger adapted to straddle the notched flange and a projection upon the hanger adapted to enter the notch.

3. A support for cables and the like, comprising a notched bracket and ahanger adapted to be attached to the bracket, such hanger consisting of back portion, a shelf portion extending outward from the back, a rearinu'dly extending flange located toward each side of the back portion and a pin carried by and extending between the flanges and adapted to enter one of the notches oi the bracket.

a. A support for cables and the like, comprising an angle-iron bracket, one flange of which has a notch extending inwardly and downwardly from the outer edge thereof and a hanger consisting of a back, a shelf extending outward from the back and a flange extending rearward from near each side of said back and a pin carried by and extending between the rearwardly extending flanges at a point spaced from the back of the hanger, said rear flanges being adapted to flank the notched flange of the bracket and the pin being adapted to enter one of. said notches.

In testimony whereof, I have signed my name to this specification.
